Abstract

New higher precision measurements of the hyperfine Zeeman transitions in the ground state of muonium have been performed with use of the high-stopping-density surface μ+ beam at the Clinton P. Anderson Meson Physics Facility. The results are Δν=4 463-302.88(16) kHz (0.036 ppm) and μμμp=3.183 346 1(11) (0.36 ppm). The current theoretical value of Δν agrees well with experiment within the 0.77-ppm error of Δνtheor, which is due principally to inaccuracy in evaluation of the nonrecoil radiative correction term. The most precise current value of mμme is obtained from our value of μμμp.
